Join 0.3-0.8 parts of agent；
（2）By nano-sized magnesium hydroxide and epidesmine powder by after proportioning mixing under conditions of 280-320 DEG C freeze-day with constant temperature 4 hours
To constant weight, silane coupler is obtained into the weak solution that mass concentration is 0.5-0.8% with absolute ethyl alcohol dilution, with nanometer titanium dioxide
Silicon, the stirring mixing of epidesmine powder, are dried to constant weight after ultrasonic disperse, ground 80 mesh sieve, with medium molecular weight polyvinyl, poly-
It is put into after etherimide, PEN mixing in Multidirectional motion batch mixer batch mixing 6-8 hours, controls the heating-up temperature to be
135-150 DEG C, molten condition mixture is extruded, be extruded into fishing net monofilament, it is rolled, tie up, obtain fishing net after knitmesh.
As further improvement of these options, the weak solution, nano silicon and epidesmine powder use electricity
Dynamic mixer is stirred 1.5-2 hours and mixed.
As further improvement of these options, the condition of the ultrasonic disperse is the concussion point in ultrasonic oscillation instrument
Dissipate 30 minutes.
As further improvement of these options, the medium molecular weight polyvinyl is using the preceding condition at 105 DEG C
Lower drying 4 hours, grinds to form 200-240 mesh powder.
As further improvement of these options, the silane coupler be gamma-aminopropyl-triethoxy-silane, γ-
（Methacryloxypropyl）Propyl trimethoxy silicane, N- β-（Aminoethyl）It is any in-γ-aminopropyltriethoxy dimethoxysilane
It is a kind of.
As further improvement of these options, gained melt is in length after the molten condition mixture extrusion
0.6-0.8m, water temperature is cooling in 15-20 DEG C of tank.
The present invention has advantages below compared with prior art：
Nano-sized magnesium hydroxide can improve fretting wear and the erosion wear resistance of fishing net, and epidesmine powder can improve fishing to a certain extent
The heat endurance and friction resistant croop property of net, are handled through silane coupler, and nano-sized magnesium hydroxide and epidesmine powder can be more preferably
Combined with matrix, transmission is met with stresses, the hole of effective filled composite materials, and the work of the strong point is served as in the composite
With the compression performance of improvement composite prevents the insertion and cutting of abrasive particle, so as to improve the wearability of composite；Luxuriant gold
Category polyethylene has more straight chain, and the crystallinity of blend can improved to a certain degree by coordinating with PEI, appropriate
Under the conditions of, 3 times can be improved in -30 DEG C of impact strengths, impact strength can improve more than 2 times under normal temperature；There is gained fishing net
Stronger wearability and wind and wave resistance performance, impact strength retentivity is good under Exposure to Sunlight or cryogenic conditions, compared to common PA fibers
With obvious fracture strength advantage, and with certain antibiotic property and resistance to soiling, extend the usage cycles of fishing net.
